Our Assessment: This is one hell of a setup! The Griswold Brothers heavy profile 24” barrel has bright, sharp rifling with an M.E. reading of about ZERO, and is free-floated the first 21”, in the camouflaged synthetic McMillan stock. This rifle looks to have been shot infrequently, if at all, outside of factory testing and was well taken care of in the interim. The McMillan G30 action takes .300 Winchester Magnum, with a spiral fluted bolt, which glides with fluidity. McMillan and the Griswold Brothers are two very well known and revered precision companies with a solid background in custom builds; this setup was done professionally and should make for an extremely accurate piece, with the addition of your favorite optic and mounting system. This rifle should ring true for long distance shooting and would be just as well suited for hunting larger game. From Wikipedia “Compared with the 30-06 Springfield the .300 Winchester Magnum provides a nearly 300 ft/s (91 m/s) increase in velocity. This translates to about 20% greater energy advantage over the 30-06 Springfield cartridge. Due to the short neck, heavier bullets particularly those weighing greater than 200 grains (13 g) and mono-metal bullets such as the Barnes X bullets will need to be seated more deeply into the cartridge. As the bullet will take up volume which could have been taken by the propellant velocity advantages diminish as the weight of the bullet increases. The .300 Winchester Magnum is known for its accuracy and has been used for 1,000-yard (910 m) and 1,000-metre (1,100 yd) competitions. While in hunting situations such accuracy is unnecessary, such accuracy does aid in the extending the range of the cartridge. Taken together with its performance it remains one of the most useful and popular cartridges today.” The cartridge was championed by the legendary American Sniper, Chris Kyle, who claimed it to be one of the best rounds ever made.
